Important Notes: 

• The three first sessions will be dedicated to one specific topic according to the main subjects of the workshop.
• Each paper will have 10 to 15 minutes for presentation, apart from questions. The rest of each session (45-60 min. approx.) will be dedicated to discuss about the problems, questions and hot issues of the specific topic being dealt with. 
• One of the exercises in this second part is also to select some of these hot issues being discussed, in order to concentrate on the most interesting ones during the last session. 
• In the last session, depending on the number of attendees and their preferences, we could either split in groups, focusing each group in one of the identified issues, or deal with them collectively. 
• All participants are kindly requested to read the workshop papers so  presenters can concentrate on the major contributions of their papers and the open issues they identify. 
• Besides, please send us a list of the topics or questions that you would like to discuss during the workshop (should they be related to your paper or not) before Wednesday 9/6/99. 
• Please, confirm your participation as soon as possible.
